    Welcome to the PF.

    What's a battery discharger? Can you post a link to one? Why do *you* think they might be heavy?

    Dear Beckerman;

    Find here a link so you can see an industrial battery discharger.

    Battery dischargers are a group of batteries for discharging industrial batteries, since currents are high (100 A for example) a lot of resistors are needed and the equipment can weight 60 kg.

    Regards,
